two SonicWalls VPN site to site APs are not seeing the Aruba controller what am i missing

I Have two SonicWalls a 4600 and a 3600 with a VPN connection the aruba control sits behind the 4600. I would think that the aruba controler would see the two APs at the secound site threw the VPN. Do I need to set something up on the controler for it to see the APs?

What discovery method is the AP using to find the controller?  You should start with that...

Your existing access points, are they on the same VLAN as the controller?  In that case, they can easily find the controller through broadcasts.  If an access point is on the other side of a VPN tunnel they are not on the same VLAN as the controller and you would need to have an "aruba-master.<your domain>" a-record in DNS so that they find the controller.  Please see the video here:  http://community.arubanetworks.com/t5/Unified-Wired-Wireless-Access/Why-Doesn-t-My-Aruba-Access-Point-Find-My-Controller-Part-1-7-05/m-p/18906/highlight/true#M11041

no two difrent Vlans the controler is 192.168.0.1 the second site is on 192.168.100.1. the sonic wall acts as the DHCP at the second site. At the main site the server acts as the the DHCP. 

 

I read the post not sure were to look on the dashboard to find the settings. Is it under Configurations/ network/ controler

School_IT,

It is not in the controller. Your DNS server needs to have an A-record of "Aruba I master" pointing to your Aruba controller. The access point boots up and puts aruba-master in front of whatever domain your dhcp server supplies and attempts to resolve it as the IP address of the controller..

now I see it the sonicWall needs to point to the DNS server that points to the aruba controler threw the VPN
